However, the liquid crystal display device having such a structure cannot be applied to a so-called externally-charged liquid crystal display, in which recording and erasing can be realized from the outer surface of the display screen. As an improvement in this respect, Japanese Patent Application Laid-open Nos. (Sho) 61-83521 and (hei) 3-4371 5 disclose a liquid crystal display device including a polymer layer with liquid crystal dispersion in which the liquid crystal is finely dispersed by the liquid crystal In the polymer matrix and covering a conductive layer into a layer; and an image display method in which the recorded image is provided with static charge from the outside of the polymer layer with liquid crystal dispersion from the display shell on the display shell Therefore, the phase and / or alignment of the liquid crystal is changed to form 0.

The liquid crystal dispersed polymer layer as a component of the externally charged liquid crystal display device of the present invention includes finely dispersed liquid crystal into its polymer matrix. As a preferable feature of this layer, in order to improve the volume resistivity of the polymer layer in which the liquid crystal is dispersed, droplets of liquid crystal are finely and individually dispersed into its polymer matrix. The polymer / liquid crystal ratio in the liquid crystal dispersed polymer layer is in the range of 9/1 to 1/9 and is preferably from 7/3 to 5/5. Because finely dispersed liquid crystal droplets with very large or very small sizes reduce the performance of clear white / unclear for the recorded layer, the size range should be preferably from about 0.1 to 20 microns. The polymer layer with liquid crystal dispersion thus obtained preferably has a thickness of 1 to 50 m. The volume resistivity of the polymer layer with liquid crystal dispersion in air at 20 ° C and 90% relative humidity is preferably 1013ω · cm. For the resistivity of less than 1 013 Ω · cm, the electrostatic charge used to form the recorded image cannot be balanced between the upper and lower interfaces of the polymer layer with liquid crystal dispersion, and it is easy to move. Therefore, over time In the past, the outline of the recorded image became steam without clarity. As the polymer used in the polymer layer with liquid crystal dispersion, various vinyl resins such as polyvinyl acetal, acrylic resin, etc .; polyester, polystyrene, polyphenylene ether, ionomers can be mentioned , Polycarbonate, polyhydrocarbon, etc. Examples include silicone polymers and polymers containing a functional group such as the following: nitrile containing double bonds, uryl groups, hydroxyl groups, carboxyl groups, epoxy groups, containing -13------------ ------------- installed ------ 1Γ ------ marry (please read the precautions on the back before filling out this page) 214582 A6 B6 Central Bureau of Standards, Ministry of Economic Affairs Printed by Employee Consumer Cooperative V.

The cross-linked polymer may be mixed with a cross-linking agent which reacts the polymer having one of the aforementioned functional groups with the functional group to cause a reaction therebetween, or via reactive polymerization of the polymer having one of the aforementioned functional groups It is obtained by mixing the materials and forming a reaction therebetween. At elevated temperatures, the cross-linked polymer does not show any miscibility with liquid crystals so that the finely dispersed liquid crystal structure can be maintained stable. Therefore, the polymer layer into which the liquid crystal is dispersed becomes long-lasting, and there is no deterioration in performance after the passage of time. Examples of the crosslinking agent used in the above reaction include: organic peroxides, amine compounds, aziridine compounds, epoxy compounds, dicarboxylic acids or carboxylic acid anhydrides, formaldehyde, dialdehydes, diols, bisphenols , Silanol compounds, metal oxides, metal compounds, photocrosslinkers (photopolymerization initiators), etc. Examples of reactive polymers include phenolic resins, amine-based resins, polyisofluorates, polyols, epoxy resins, and the like.

The liquid crystal needs to have a mesocrystal temperature of 10 to 100 to match the actual application as a liquid crystal panel, and it should have a birefringence index of 0.2 or more △ !! or greater, in order to improve the liquid crystal Turbidity (it has the function of making the recorded image clear). Liquid crystals can be added with a dichroic dye as needed. The liquid crystal dispersed into the polymer matrix can be implemented through the following methods: polymer / liquid crystal common solvent evaporation separation method (common solvent molding method), polymerization phase separation method (where the precursor mixture of liquid crystal and polymer is passed through Light or heat to polymerize), melt-cooled phase separation method (in which liquid crystal and polymer are melted by heating and then cooled), or by microencapsulating liquid crystal and dispersing it into the polymer. A transparent polymer having high resistance can be used as the transparent chloroplast layer for the liquid crystal panel of the present invention.

The volume resistivity is 1 013Ω · cm or more at 90% relative humidity and at 20 ° C in air. This layer is more certain to prevent the movement and attenuation of static charges held on the upper and lower interfaces of the polymer layer with liquid crystal dispersion, so that it can improve the outline definition of the recorded image, memory retention, and erasability And other aspects of performance. For the same reason as described for the polymer layer with liquid crystal dispersion, a material having a volume resistivity of 1013Ω · cm or less in 90% relative humidity and 20 ° C air is used as the transparent high resistance layer A problem arises in terms of its performance and therefore, the liquid crystal panel thus obtained cannot meet practical applications.

The display device for recording images used in the hand-writable liquid crystal panel device of the present invention uses a recording member electrically connected to one terminal of a power source, and at its other terminal, it is connected to the conductive layer of the liquid crystal panel to produce a surface The electric potential is between the surface of the liquid crystal panel and the conductive layer. When the recording member is brought into contact with the board of the liquid crystal panel, a recorded image may be formed. If the surface potential is generated on the board, the liquid crystal present in the polymer layer with liquid crystal dispersion is aligned by the electrostatic field, so that the aligned part becomes transparent in the white-turbid board. Therefore, an image with high contrast is formed. When the surface potential is less than a fixed limit level (higher than this level, the liquid crystal in the liquid crystal dispersed polymer is aligned), the liquid crystal cannot be fully aligned and it is completely transparent. As a result, the recorded image has poor contrast. The erasing device for erasing the recorded image in the hand-writable liquid crystal panel device of the present invention includes an erasing member electrically connected to the conductive layer of the liquid crystal panel. When the erasing member is brought into contact with the recorded image on the board (or more precisely, with the image on the surface of the transparent insulator layer of the liquid crystal panel), the recorded image and the conductive layer become equipotential Therefore, it is easy to remove the static charge existing in the recorded image to erase the recorded image.

Invention description (16) Materials. When the drawing or erasing operation is implemented using a display or erasing device composed of a conductor with a resistivity of 1 012 Ω · cm or less, it may smoothly provide static charge on the board to align the liquid crystal, or It is easy to remove the static charge and return from the aligned state to the initial state of the liquid crystal. As a result, images with high contrast and smooth erasing performance can be easily obtained. On the other hand, if the volume resistivity of the conductor exceeds 1 0 12 Ω · C ΙΏ, the contrast of the recorded image becomes firm, the response becomes blurred, and the erasability becomes insufficient to obtain the desired erasability Unless the erasing operation is repeated many times. This trend is unsuitable for hand-written LCD panel devices. In the present invention, for example, a transparent image is mainly formed on the white / cloudy background of the board. However, the white-turbidity image, relative to the original display, can also be obtained in the transparent plate. This can be achieved by firstly providing the static charge on the board by the recording member to align the liquid crystal, and secondly by removing the static charge from the board by the erasing member. In the hand-writable liquid crystal panel device of the present invention, the recording member used in the display device and the erasing member used in the erasing device are each electrically connected to the power source and the conductive layer. Here, the electrical connection must not be assumed to be connected via a lead. For example, the human body is electrically conductive, so that part of the human body may be used for painting and erasing.

The power source in the board device of the present invention is preferably composed of a substantially current source, which provides a potential difference between the conductive layer and the recording member, so as to generate a surface potential on the board. You can use any power supply or even a solar battery pack, as long as it meets the above requirements.

Description of Invention (19) Between the terminal on the side of the erasing member of the source and the erasing member, and between the conductive layer and the erasing member. These resistors provide an improved safety to the handwriting liquid crystal device, so if the display device and / or the erasing device are brought into contact with the operator's body, there may be no electrical shock. As far as the generated voltage of 50 to 100 volts is concerned, the resistance used here is allowed to range from 2 Ο ΟΚΩ to 1 Ο ΟΜΩ, and it is more preferable to be limited to the range from 1 ΜΩ to 4 ΟΜΩ. The reason for limiting the resistance in this range is because if any component of the display and erasure equipment is brought into contact with the human body through a resistance of less than 2 Ο Ο ΚΩ when a 100 volt power supply is used, electrical shock will occur to On it. On the other hand, if a resistance exceeding 100 ΜΩ is used, current leakage will occur due to the relationship with other insulation resistances such as the substrate, resulting in a voltage drop in the generated voltage, or a response to display and erase operations The degradation caused by the failure of the smooth operation of display and erasure. Because the hand-writable liquid crystal panel device is configured with interlocking devices and resistance-based protection against electric shock, the panel device is greatly improved in safety and can be used by anyone without fear or discomfort. The handwritten liquid crystal panel device with such greatly improved security can be applied to a cordless type device. In a cordless type hand-writable liquid crystal panel device, the power supply is connected to a conductive layer at one terminal thereof and the other terminal of the power supply is connected to a surface electrode through a resistor. It is used as a button for a switch for recording. The conductive layer is also connected to another surface electrode through a resistor. It is used as a button for a switch for erasing.

Description of invention (20) A series of a contacts for erasing switches, and a series of a contacts for recording hand switches and for erasing A series of force points of the switch are connected to another terminal of the power supply. With this configuration, pressing it with the left hand to touch the surface electrode for the switch for recording, an operator can draw a recording image by touching the surface of the panel with the right hand itself or holding the recording member in the right hand. On the other hand, pressing it with the left hand touches the surface electrode of the switch for erasing, and an operator can erase the recorded image by touching the surface of the panel with the right hand itself or holding the erasing member in the right hand. In both cases, there is no need to draw out the wire, so even if the display and erase are repeated many times, there is no fear: the wires are entangled or broken, thus allowing the hand-writable liquid crystal panel device to be simple and difficult to collapse. In the hand-writable liquid crystal panel device of the present invention, an automatic power-off device can be provided on the circuit for the display device. Because after a predetermined period of time, if the switch stays in the conductive state, the device can automatically cut off the power switch, so the device may be power-saving without wasting power. In the hand-writeable liquid crystal of the present invention In the board device, members such as boards and recording and erasing can be impregnated or covered with an oil. Another way is to cover a piece of polymer film on these items. With these treatments, the board will be difficult to stain.

Description of the invention (21) The oil, sweat, cosmetics or any other stains left on the hands on the gimmicks have moved for a long time. This may cause the applied static charge to move easily and thus decay, leading to the deterioration of the sharpness of the outline of the recorded image and reducing the memory retention and erasability. The above-mentioned treatment acts to remove or prevent such adverse effects. In the hand-writable liquid crystal panel device of the present invention, the display and erasing of the recorded image are implemented based on one of the following principles: the existence of the electrostatic field and the absence of the liquid crystal dispersed polymer layer of the liquid crystal panel to create transparency And opaque state on the external charging type liquid crystal display device. More specifically, the liquid crystal droplets in the polymer layer with liquid crystal dispersion are finely dispersed into its polymer matrix and the liquid crystals are aligned along the polymer wall. Therefore, when no static charge is supplied, the difference in refractive index between the polymer and the liquid crystal causes light scattering and makes the liquid crystal panel white / turbid or opaque. On the other hand, if an electric field is applied to a polymer layer having liquid crystal dispersion through a transparent chloroplast layer through a display device, the liquid crystal is oriented in the direction of the electric field. Through this alignment, the refractive indexes in the polymer and the liquid crystal become substantially the same as each other. As a result, light scattering is suppressed to create a transparent area, or a contrast is generated between the board and the recorded image so that the board is displayed (Figure 1). In order to erase the image, the electric field created in the polymer layer with dispersed liquid crystal is removed by an erasing device. Through this operation, the liquid crystal is brought back to the initial state or the state in which no electric charge exists, and the light is scattered again, causing the board to appear white / turbid (Figure 3). According to the hand-writable liquid crystal panel device of the present invention having the above-mentioned configuration, for anyone who can make a simple display and erasing device such as a hand, it is easy to write and draw images by hand and erase recorded images without complicated The device and redundant paper scale are applicable to China National Standard (CNS) A4 specifications (210 X 297 public goods) -24-82. 3. 40,000 ------------------------ Pretend ------ TΓ ------ Marry (please read the precautions on the back first, then 塡Write this page) Printed 3 clothes 214532 A6 B6 by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs.

Instructions for the invention (22) Long operation In addition, even if the electric operation is performed during display and erasing, that is, supply and removal of electric charges, the board device is excellent in safety without fear of causing electric shock to the human body. According to the earlier technique, a liquid crystal display device is formed so that: a polymer layer with liquid crystal dispersion is directly laminated on the conductive layer. In such a liquid crystal display device, the supply of electrostatic charge is implemented by various methods, for example, voltage application, corona discharge, contact charge, etc. Therefore, an electric field is generated in each part (where, Provided with charge). Although the electric field generated in this way aligns the liquid crystal to form an image, the electrostatic charge moves and thus decays with time. In other words, the electric field decays and disappears with time, so that the alignment of the nematic liquid crystal is brought back to the initial state, resulting in insufficient memory performance as a display device. However, in the present invention, the high-resistance layer is disposed between the conductive layer and the polymer layer with liquid crystal dispersion, so that the memory retention performance is significantly improved. This phenomenon can be considered as: the high-resistance layer prevents the movement of static charge and maintains the electric field of the recorded image (Figure 2), thus providing excellent performance in memory retention of the recorded image, which cannot be achieved through traditional construction To get. In the liquid crystal display device of the present invention, the static charge in the recorded image part can be easily removed by electrically connecting the conductive layer and the part of the recorded image or the surface of the transparent chloroplast layer so that these two parts may be Equipotential. As a result, the electric field disappears and the liquid crystal alignment returns to the initial state. In short, erasing recorded images can be implemented in a simple way (Figure 3). In the traditional liquid crystal display device, the static charge in the polymer layer with liquid crystal dispersion staying on the surface of the conductive layer moves and decays with the passage of time '.

Such an imbalance of electric charges is difficult to remove or eliminate the electric field from the surface of the transparent insulator layer, resulting in poor erasability. However, in the present invention, supplying a transparent high resistance layer also improves erasability. This phenomenon can be considered that the high-resistance layer suppresses the movement of static charge, while maintaining the balance of the amount of static charge between the upper and lower isosurfaces of the polymer layer with liquid crystal dispersion, thus providing an excellent erasable recorded image Except for sex, it is not available through traditional construction. Generally, the transparent insulator layer is provided for the purpose of protecting the polymer layer in which liquid crystal is dispersed when recording and erasing are performed. That is, the supply is to prevent the polymer layer with liquid crystal dispersion (which serves as a display screen) from being easily damaged due to friction and wear through other members. However, the supply of a transparent insulator layer also prevents the electrostatic charge from dispersing the polymer layer of liquid crystal dispersion even at high humidity, especially in air at 20 ° C and 90% relative humidity. This makes the recorded image clear without blurring its outline over time, and improves memory retention performance and the erasability of the recorded image. This phenomenon can be considered as: the transparent insulator layer maintains the balance of the amount of electrostatic charge between the upper and lower isosurfaces of the polymer layer in which the liquid crystal is dispersed. According to the present invention, in a hand-writable liquid crystal panel device, a large-size board can be provided and the image display and erasing can be performed from the outside of the board, due to the characteristics of the externally charged liquid crystal panel used . In addition, the recorded image has excellent memory retention performance and the liquid crystal panel has sufficient durability for practical use.
